Hi,Thank you for the quick response, I will keep an eye on the response ofgnulib team.

Post by Paul EggertThanks for the bug report <https://bugs.gnu.org/25821>. I'm forwardingthis to bug-gnulib, as it is apparently a bug in the Gnulib lockmodule's implementation on the Hurd.This bug does not affect grep per se, as it's a Gnulib test-harnessbug and not a Grep bug. I'm therefore closing the Grep bug report.
